DETAILED DESCRIPTION OF THE EMBODIMENTS

FIG. 1 is a flow diagram of a method for recalling an image file according to an exemplary embodiment. As shown in FIG. 1, the method for recalling the image file is applied to a mobile terminal and includes the following steps.

In S11, receiving a notification message sent from a server for prompting that a target image file is recalled.

In some embodiments, a sender initiates a request for sending an image carrying the target image file to the server, and the server sends the target image file to a receiver after receiving the target image file. The sender initiates a recalling request for the target image file to the server within an allowable time range during which the recalling is allowed, and the server sends the notification message for prompting that the target image file is recalled to the receiver after receiving the recalling request and recalls the target image file. Further, in some embodiments, the target image file includes, but is not limited to an image, a video, a song and an animoji.

In S12, determining whether the target image file is open based on the notification message.

A main purpose of the present disclosure is to solve the problem of unsmooth display brought by sudden recall of the target image file when the target image file received by a user as the receiver is displayed in a full screen. Therefore, in some embodiments, after the receiver receives the notification message, it is necessary to determine whether the target image file is open, and if it is determined that the target image file is open, a subsequent replacement operation is executed.

In some embodiments, it is assumed that a user B sends an image to a user A. After receiving the image, the user A selects to click on the image, at the moment, the image is displayed in a full screen. The user B may select to recall the sending of the image within the allowable time range during which the recalling is allowed, a system automatically sends a push notification to a mobile phone of user A to prompt that the image needs to be recalled, and meanwhile, a replacement image is carried to mark that the viewing of the current image is blocked. At the moment, the mobile phone of the user A may determine whether the user A has opened the received image and displayed the image in the full screen, if so, the received replacement image is automatically used as a new layer to be displayed on the current image, at the moment, an original image may not be viewed. When the user A clicks on the image to return to a chat dialog box, the system has replaced the image of the user B with a default replacement image. The user A may normally see the message sent by the user B, so that it is ensured that the display experience of the user A is smooth and is not affected.

In S13, if it is determined that the target image file is open, acquiring a preset replacement image file, and displaying the replacement image file on a target image file layer.

In some embodiments, there is one or more replacement image files. Each of the replacement image files may include various elements which include, but are not limited to an animation, an image, an avatar, an emoji and text information. The replacement image file may be any single element as above or a combination of a plurality of the elements, wherein the text information is configured to express any one or more of the following contents:

-   -   a file type, such as a text or an image, of the recalled target         image file, a prompt that the display of the current target         image file is blocked and a reason why the display of the target         image file is blocked.

In some embodiments, the preset replacement image file may be stored in a server or stored in the receiver. If the replacement image file is located in the receiver, a local replacement image file is only required to be obtained for replacement during replacement. If the replacement image file is located in the server, the replacement image file carried in the notification message is extracted firstly, and then, the replacement image file is displayed on the target image file layer.

In some embodiments, the replacement image file may be preconfigured and stored in the server, may be modified or may be prestored in the receiver. In addition, the replacement image file may be automatically replaced and may be flexibly customized and is generally an image with rich pictures and characters customized by the server, including various rich contents such as an animation, an image, an emoji, a video, an avatar and text information. Moreover, the replacement image file carries information for prompting that the display of a currently browsed image file is blocked, so that a user may know that the original image is no longer available, but it doesn't seem abrupt. Optionally, the recalled image or text may be further marked in the replacement image file, and thus, the user experience is improved.

Further, the replacement image file may be one or more image files preconfigured in the server, and one or more of the configured image files may be modified. If there are a plurality of the replacement image files, priorities or a replacement order of the replacement image files may be set. If image files are required to be replaced, it is possible that corresponding image files are obtained according to the preset the priorities so as to be replaced or the replacement image files are sequentially obtained according to the preset replacement order so as to be replaced; or it is possible that the priorities of the plurality of replacement image files are set or modified, and therefore, if the replacement image files are subsequently sent to the receiver by the server and are replaced, the replacement image file with the higher priority may be sent according to the priorities.

In some embodiments, if the replacement image files are locally stored, a setting request for a replacement order of the plurality of the replacement image files is received, and the replacement order is set for all the replacement image files, so that the corresponding replacement image files are sequentially obtained for replacement display according to the preset replacement order during subsequent replacement, and automatic replacement is realized. For example, a replacement order of three images A, B and C is preset as A-B-C, if a current replacement image is A, software in the present disclosure records an identifier of the current replacement image, and if the image file is required to be replaced next time, a current replacement image file is determined according to the recorded identifier of the last replacement image file, and so on. According to the present disclosure, it is ensured that several continuous replacement image files are inconsistent due to the adoption of such a replacement mechanism, so that freshness is brought for the users, user experience is improved, and the phenomenon that the same replacement image is adopted every time to result in boredom from the users is avoided.

According to the present disclosure, if the sender has recalled the sent target image file, the recalled target image file may be replaced with the preset replacement image file, so that it is ensured that the display experience of the user of the receiver is smooth, the problem of unsmooth browsing experience of the user due to sudden recall of an image file when the user browses the image file is solved, and the user experience is improved.
